In this work, plasmonic nanostructures are implemented to make Raman spectroscopy into a surface-sensitive technique for the study of adsorbates on a catalyst surface. In particular, Au and Ag nanoparticles are isolated with SiO­2 and TiO2 coatings to obtain thermally Raman signal enhancers.[1] This technique is referred to as shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS).[2] Solid metals are assembled over the shell-isolated nanoparticles by wet-impregnation for the study of hydrogenation catalysis.[3]
